If you don’t already have the Citi Dividend or Chase Cash Plus Rewards credit card, GO APPLY! Both have a full 5% cash back on purchases at supermarkets, drugstores and gas stations, plus 1% on all other purchases. You don’t need to care about the 1% since most cards already offer that. The catch is both are limited to $300 cash back per year, so get both and now that restriction goes up to $600 per year. Currently Chase is holding a promotion: $100 bonus cash back check when you sign up (from FW)!!! I only had a $50 bonus when I signed up. The offer code is 94B and expires 4/30/2006.
For those who eat out a lot or travel a lot, might also went to invest in a Costco American Express card. That gives you 3% at restaurants (including bars) and 2% on all travel. I think they count movie theaters as “restaurants”, but don’t quote me on that because I recall seeing it listed under that category once on my bill. There’s a catch though. The cash back on the Amex is in the form of a gift certificate you can use at Costco and comes once a year (every February).
